ALARM-CLOCK.

SPECIFICATION forming part of Letters Patent No. 549,242, dated November5, 1895.

Application filed April 26, 1895- To @ZZ whom t may concern:

Be it known that I, ALMERON M. LANE, a citizen of the United States,residing at Meriden, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inClocks, of which the following is a speciiication.

My invention relates to improvements in clocks having bell-ringingmechanism, and the main object of my improvement is to more convenientlyarrange the movement and its bell-ringing mechanism for removal from thecase for the purpose of repairs, and also to arrange the bell on theback of the case at the outside, whereby the appearance of the clock isimproved and a better-sounding bell may be employed.

This application is a substitute for one formerly liled by me as SerialNo. 513,201, filed .I une 1, 1894, which is withdrawn and abandoned infavor of this application.

In the accompanying drawings, Figure 1 is a front elevation of my clock.Fig. 2 is a rear elevation of the same. Fig. is a central verticalsection of the same with some of the central parts in elevation and theupper portion of the sash broken away in order to better show theholding-ring. Fig. 4 is a sectional view of a portion of the case andone of the feet, the holdingscrew and rivet being shown in elevation,although they come within the plane of section. Fig. 5 is a view of theunder side of one of the feet and a portion of the case. Fig. 6 is arear View of a portion of the movement, showing mainly the hammer andthe dust-cap. Fig. 7 is a detached side elevation of the movement an dconnected parts a-s removed from the case. Fig. S is a front view of thesame with the pointers and dial removed, the sash. being represented asopen and broken oit. A portion of the front plate adjacent to therevolving-hammer shaft is also brokenout. The parts in the extremedistance at the back part of the clock are not shown.

The clock shown in the drawings is designed particularly as analarm-clock; but my im provement is equally as applicable to clockshaving a bell-ringing mechanism for ringing the several hours of the dayas it is to a clock for striking the bell at some particular hour forwhich it may be set.

Serial No. 547,213. (No model.)

A designates the case,which I prefer to form of sheet metal and of acylindrical form. Its back on the inside is provided with areinforcing-plate 9, and in the center of the back at the outside is thebell-post 10, to which the bell B is secured so as to stand concentricto the case and on the outside thereof at its back. This back is alsoprovided with a circular hole 11, Fig. 3, through which the revolvinghammer 12 of the bell-ringing mechanism may readily pass, even when saidhammer is in the act of revolving.

In the front of the case I lit the iianged holdin g-ring 13, thecylindrical portion of said ring beingtted within the inside of thecylindrical case loosely enough so that it may readily be slid into andout of the case by hand, and yet snugly enough so that the sides of thecase may in part control its'position therein. The front flange of thisring-that is, the iiange which stands at a right angle to itscylindrical portion-has the front ends of the arms or brackets 14permanently secured to it, while the other ends of said brackets havethe front movement-plate permanently secured to them. On the front ofthis iiange I also secure the finishing ring or scalp 15, which is of alarger diameter than the ring 13, and consequently is as large or largerthan the diameter of the case, so that it forms a shoulder for the frontedge of the case to abut against and govern the depth that the ringshall be slid into the case. To this finishing and holding ring onehinge-leaf of the sash 1G is secured.

The particular construction of the movement herein shown is made thesubject of another application of even date herewith, and consequentlyneed not be herein particularly described. It is, however, all rmlyconnected with and carried by the front movement-plate 17, which in turnis permanently mounted on the holdingring 13, the movement-plates beingof less diameter than the cylindrical portion of said ring and notbearing on the case, so that the entire support of the entire movementand its bellringing' mechanism is through said holding ring. Any knownmovement carrying rearwardlyprojecting striking devices adapted tostrike a concentric bell on the outside of the case at the back whenthus wholly supported on IOO ' pose of this invention.

I secure the cylindrical portion of the removable holding-ring directlyto the side of the case by a screw 18, Fig. 3, at the top of the caseand screws 19 at the bottom of the case. The feet 2O are of sheet metalbent at a right angle with one member riveted to the case, as at 21,Figs. 4 and 5, the holding-screws 19 also passing through this member ofthe feet,

thereby making the screws which hold the holding-ring and movement alsoassist in more rigidly holding the feet.

The revolving hammer is mounted on the shaft 22, suitably connected withthe drivingtrain and carrying at one point a ratchetwheel 23 and at itsforward end a revolving` arm 24e. An ordinary trip 25, operated throughthe dial-wheels and ordinary alarm setting and releasing devices, ofwhich it forms a part, is forced into the path of this arm 24 to preventthe hammer-shaft from revolving and at the proper time for which thealarm may be set withdrawn therefrom in the usual manner to permit thehammer to operate. A spring 30 bears upon the ratchetwheel 23 of thehammer-shaft in order to prevent the hammer from revolving backwardlywhen the alarm movement is being wound.

The hammer-shaft passes through the hole in the back of the case, butwithout any bearing contact therewith and substantially at the center ofsaid hole.

Arranged to slide loosely on a hollow stud 31, Fig. 3, that projectsfrom the rear movement-plate 27 and within which stud the hammer-shaftrotates, there is a sliding hub or collar 2G, and on said hub is adust-cap 2S, large enough to cover the hole in the back of the case,against which back it is snugly pressed when the movement is within thecase by means of the spiral spring 29.

By securing all of the internal parts to the removable holding-ring Ican readily withdraw the movement from the case for the purpose ofrepairs without removing the sash or the pointers or dial, and I caneven take out and putin the movement when the striking hammer is moving.Even when the movement is taken wholly apart it is not necessary or evendesirable to remove the holding-ring from the front plate. In fact Iintend to rivet the brackets to said holdingring and front plate, sothat they cannot be separated without removing the rivet-heads.

By placing the bell upon the back of the case and extending the strikerthrough a hole in the back of said case, the winding parts being at thefront, I produce a clock in which there is practically no limit to thediameter of the bell inside the diameter of the case, so that a verylarge bell may be combined with the clock in a very compact andsymmetrical form.

By the employment of a spring-pressed dust-cap connected with thestriking movement and a large hole in the back of the case I canconveniently remove the striking or bell-ringing mechanism with the restof the movement, and I effectually stop up the hole for excluding dustby the mere act of putting the movement into the case, and the entiremovement may be removed without removing the bell.

I claim as my invention- 1. A clock comprising a cylindrical case, aholding ring having a cylindrical portion fitted to slide into and outof said case, an outwardly projecting or external shoulder at the frontof said holding ring for abutting against the front edge of the case,the sash hinged to the outwardly projecting portion of said holdingring, the movement secured through its front plate to said holding ring,the movement plates being of less diameter than the cylindrical portionof said ring, and devices for fastening said ring to the sides of saidcase, substantially as described and for the purpose specified.

2. A clock comprising a case with a large hole in its back, a movementmainly within said case but having a hammer projected through said holeto a position without the case at the back and a yielding dust capmounted on the movement for covering said hole, substantially asdescribed and for the purpose specified.

3. A clock comprising a case, a dial at the front of said case, amovement mainly within said case but having a hammer projected therefromto the outside of the case at the back, and a bell concentricallymounted outside of the case on a post which stands at right angles tothe plane of said back and dial, the hammer being in proper positionwithin said bell for ringing it, substantially as described and for thepurpose specified.
